The blockchain network is a modern technology that first emerged with Bitcoin in 2009, but it is no longer limited to digital currencies only. It can be defined as a distributed database that acts as a shared digital ledger among a large number of connected computers. It is characterized by being decentralized, meaning it is not controlled by a single entity, but is managed collectively by users.

Data is recorded on the blockchain in the form of blocks, and each block is linked to the previous block by strong encryption algorithms, making it almost impossible to change any information without the consent of the entire network. This feature gives it a high degree of transparency and security.

Blockchain is currently used in various fields such as: digital currencies, smart contracts, supply chains, electronic voting, and even in the medical field to secure records. Thanks to its distributed and secure nature, blockchain is one of the most prominent technologies that could change the future of digital economy and data management.
